WebFeb 7, 2024 · To answer your example question, there are 3.13 × 10 23 atoms in 32.80 grams of copper. Steps 2 and 3 can be combined. Set it up like the following: 32.80 g of Cu × 1 mol Cu / 159.17 g Cu × 6.022 x 10 23 atoms / 1 mol of Cu = 3.13 x 10 23 atoms in 32.80 grams of copper. Several online sites have a number of atoms calculator. WebThis isn’t good because we can’t have fractions of an atom in a molecule. Moving on, if there are two atoms of S in the molecule, 254.11−2×32.0618.99=10.00 atoms of F and we are on to something. You can check a few more cases with 3 or 4 atoms of S per molecule, but you’re going to find none of them give a whole number of F atoms.
